Hi Sana, welcome to the BigBlueBall.
We do have an IRC chat here, click under the "Community" tab to check it out.
When you say "shot" box do you mean "shout" box? We do not have one of those...but we may possibly create an IMing system on the forums in the future. You could also leave a person a message on their profile page, in the "Visitor Messages" box, if you'd like. So, in a sense, it is like a mini shout box, if you will.
